Source: brondell.com (verified 2026-07-11) · corroborated by bath4all.com. The Brondell manufacturer product page confirms the exact model via "Model Number/SKU: RC100" and states Current Price $449.99 (sale_badge: no), Storage Capacity 1.6 gallons (6.0 liters), superior 4-stage filtration, that it "operates without electricity", certification to NSF/ANSI 42, 53, 58, and 372, and filter changes at "6 and 24 months" (the 24-month interval being the RO membrane). The Bath4All retailer page corroborates the same model (Model Number: RC100), the $449.99 price, certified four-stage filtration, non-electrical design, NSF/ANSI 42/53/58/372 certification, and explicitly that the "RO Membrane filter lasts 2 years (24 months)". Rated GPD, TDS-reduction %, a numeric pure-to-drain ratio, and annual filter cost were not stated verbatim on any fetched page (the spec/performance-data PDFs were Flate-compressed and non-extractable), so those specKeys are left null; the manufacturer's "Rated Capacity: 3,500 gallons for Aesthetic Chlorine; 243 gallons for VOCs" is filter service life, not a GPD figure, so it does not populate ratedCapacityGpd.
